LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 316,422, dated April21, 1885.

Application filed February 23, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I. GEORGE H. WrLsoN, a citizen of the United States ofAmerica, residing in the city of St. Louis, and State of Missouri, haveinvented certain new and useful Improvements in Lamps, of which the following is a specification, reference being had therein to theaccompanying drawings.

My invention has reference to lamp-burners of the Argandtype; and itsobject is to secure in a cheap and compact device capable of beingattached to any lamp all the excellences which are now found only in thebest and most expensive lamps. To this end it provides means for feedingair to both sides of the wick to aid combustion, for raising andlowering the wick evenly and without catching, for promoting thecirculation of the oil,

and for spreading the flame and producing a white light. I

In the drawings which accompany and form a part of this specification,Figure l is a sectional elevation of my improved burner. Fig. 2 is aView, partly in section, of the wick-carrier and the adj listing-wheel,illustrating also the manner in which the wick is carried past theair-in1et tubes. Fig. 3 is a plan of the carrier, and Fig. 4 is asimilar view of. the bracket or support for the flame-spreader.

The outer case, A, of my burner has two rows of air-inlets, A A asshown, separated by the partition a. Each row of air-inlets consists ofa series of perforations extending horizontally around the burner.Secured within the case by friction or other means is the burner-tube A,which has an outer screwthread where it extends below the case forattaching the burner to a lamp. A central airtube, H, connecting withair-inlet tubes or passages G G, is secured within the tube A bysoldering or otherwise securing the said inlet-tubes G G intoaperturesin the said tube A. The wick, which, in practice, is made oftwo ordinary fiat wicks of the proper width, is supported between thetubes A and H. A wick-adjusting tube or carrier, I, having at each endinwardly-projecting teeth I) b, which enter the wick, holds the wick inposition, and an ordinary thumb-pinion provided with a shaft, K, and athumb-wheel, g, and properly supported in the burner, acts on theperforations I of the carrier I to raise and lower the carrier and thewick. The perforations of the carrier I are arranged in vertical rows,as shown. The perforations also serve the purpose of giving freecirculation to the oil, and so prevent the charring of the wick, whichsometimes takes place when the carrier is solid.

I have shown a carrier provided with slots or recesses I P, the top ofthe slots being arranged to rest in the lowest position of the carrieron the air-inlet tubes G G; but I may make the tube I shorter, anddispense with those portions which extend below the top of saidinlet-tubes. \Vhile I prefer the form shown and find it of greatadvantage in connection with the two rows of teeth 0 for carrying thewick past the inlet-passages with out obstruction, yet that part of myinvention which consists in providing teeth at the top and bottom of thecarrier would be of equal.

advantage in constructions where the slots or recesses would serve nofunction.

The air passes to the outer side of the wick through inlet A and passagem, and to the inner side of the same through inlets A and G G andair-tube H. To prevent the air from passing across from one inlet, G, tothe other, and so causing a downward draft through the tube H, I place adiaphragm, J, as shown,between the two inlets to deflect the air upward.

A frame consisting of tube E, arms E, and ring H supports a deflector,F, and is itself supported on the top of the tube H by a flange on theupper end of the ring, H. A shoulder, F, on the stem F of the deflector,forms the means for supporting the same on the end of the tube E.

The chimney-holder e,forming a part ofthe outer casing of the burner, isprovided with perforations f for admitting air to the passage m.

I am aware that wick raiscrs or carriers have been used or proposedhaving inwardly-prm jectingteeth at two points between the extremities;but in such cases the introduction and adjustment of the wick aredifficult, and it is impossible to have the teeth as close together asthey may be when the material at the edges of. the extremities is bentinward, and formed into teeth, which, moreover, may

be conveniently and economically done, and the greatest efficiencyobtained in that the draft upon the wick either upward or down-' wardtakes place opposite the extreme ends of 5 the carrier. Having nowdescribed my invention, what 7 I claim is- 1. In a 1amp-burner, awick-adjusting tube or carrier providedwith teeth projecting ill- 10wardly from the top and bottom edges thereof, substantially asdescribed.

2. In a lamp-burner, a wick-adjustingtu'be or carrier, I, having one ormore slots, 1", and

provided with inwardlyprojectingteeth at its top and bottom, incombination with an airtube provided with one or more air-inlets, G,whereby the wick is drawn upward with the carrier in the usual way anddownward positively past the air inlet or inlets, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.
